Main Index | Element Tree | Element Index | HTML Support History

  • Site Design Conversion to CSS1
    The entire site uses CSS1. What this means is that all non-CSS browsers will see rather boring looking pages, but the information and structure will all be intact. For CSS enabled browsers, the old color scheme is still in place for now, and can be easily changed for your own use if you decide to download it.
  • Common Attributes
    There are now many attributes that are applicable to many different elements. I have relied on existing official documentation to fill in a few gaps where I could not directly or easily test the features. The official documentation sometimes contradicts itself, so be warned that there CAN be some errors here.
  • Script
    The portion of the site that covers scripting does not go deeply into scripting. Discussion of scripting quickly gets out of the realm and scope of HTML.
  • Miscellaneous Elements and Attributes
    I have tried to document as many known elements and attributes as possible, gathered from official and semi-official resources. I also occasionally find or am alerted to unadvertised features. I do the best that I can to keep on top of this, but occasional errors occur. Also keep in mind that I have made guesses and extrapolated support information in a few cases due to missing information and lack of browser availability on different platforms. I try to stress this fact where it occurs.
  • Platform Information
    The information for this site concentrates predominantly on browsers made for the Windows platform (win32 mostly, win16 for some of the early history.) There are often significant differences in support between the various platforms, so the support and version information here will not always be valid for the respective browser version on a different platform.
  • Tag Models (Parent/Content relationships, etc.)
    The element relationship and definition models are mostly based off of the HTML 4.0 Recommendation "Loose" DTD. HTML 4.0 is the most cohesive model available to authors as of the time of writing. There are occasionally a few points of departure that I make to the HTML 4.0 model and I have tried to point out exactly WHY I chose a different interpretation when this occurs.
  • Page Validation
    As of November 1997, I have spell-checked the entire site and validated all of these pages against the HTML 4.0 "loose" DTD with the W3C HTML Validation Service. I don't do this often (I only did this once previously against HTML 3.2), so as I add or update content along the way and massage some of these pages it is possible that this may fall out of date.
  • Slight Regression in HTML/CSS Support Between previous browser versions and betas
    Most browsers have historically only added support and functionality as time progresses. But a special case occurred with Microsoft Internet Explorer. The rendering and parsing engine for IE4 was re-built from scratch. This has led to a few idiosyncrasies between the betas of IE4 and the IE3 releases. These have basically cleared up by the final release, but I try to document these discrepancies where known. (Note: The same situation also occurred with the early releases of Mozilla/Netscape 6, which also used a brand new rendering engine.)
  • Significant divergences in HTML Support Between Mosaic 3 Betas and Mosaic 3 Final
    The early Mac Mosaic 3.0 Betas had significantly different support than what is found in the final releases (eg: frames capability.) I have tried to keep this clear by noting which elements/attributes were supported in BOTH M3 Betas and final by listing support as 'M3.0' and features supported in only the betas by listing support as 'M3.0Bx.' Hopefully this is not too confusing.
